Tuning Taipan Vet huma o ring size

[Skydivingmiami]

I'm thinking my 2 main o rings on my huma are needing to be changed. Ive had to open up my taipan 177 a couple times to adjust pressure and the 2 main o rings seem a little stretched now. I tried lubing them, but I keep getting air leaking from the vent hole once I install it and add any air pressure. Does anyone know the size of the 2 main o rings that rest against the tube?



I looked for a rebuild kit online. Just couldn't find one. 



Thanks

The Huma regs are usually shipped with a rebuild kit, at least mine was. You might call Trenier, I found them helpful with a Huma question. Or, email Huma direct, I've heard they are responsive. You can also just measure them. When I have measured O rings, I was able to get within 1 or 2 increments of the right size.

If anyone needs to know the o ring size.. it’s 24mm x 2.5mm
